I had the book for a while a couple of years ago.  The main focus is on
graphics primitives.  The programs are designed to run on either machine, with
a machine specific object module for the Amiga and for the Atari ST.  If memory
serves, there were a number of graphics primitives created, from simply putting
points on the screen to moving graphics objects.  The C supported at the time
was Alcyon C, with modifications for several other C compilers which were
popular at the time (lots of IFDEFS...)  Most of the machine-specific code
revolved around the Line-A routines, if memory serves.

Once you got the machine specific stuff coded and and object module generated,
it didn't make any difference what machine you were using.

Things NOT covered:  use of resource files (not really used in Graphics
Programming anyway), VDI and AES routines (the Compute! books deals with these
in sufficient detail for rudimentary Graphics Programming, though).
